The game is played when the first player writes a new Anno to an existing idea. The Anno can be in direct response to the idea or to the annotations attached to the idea. The nature of this new Anno must be such that one can deduce the "source idea" from the information in the new Anno. Players try
to determine the "source idea" through deduction, investigation etc. The winner is the player that is able to garner the largest number of wrong guesses or who's Anno is not placed within a given deadline.

Players may use misdirection, synonyms, puns or other devices to misdirect their opponents however, vague or general Annos are not acceptable.
